How many types of rear axles does Sinotruk HOWO have?
4 Answers
Sinotruk HOWO rear axles include several models such as HW16 single-stage reduction drive axle, HW12 single-stage reduction drive axle, HC16 two-stage reduction drive axle, ST16 two-stage reduction drive axle, and STR two-stage reduction drive axle. Here is some related information about HOWO: Introduction: HOWO is a vehicle model produced by Sinotruk Jinan Truck Co., Ltd., a subsidiary of China National Heavy Duty Truck Group, and is one of the main products of Sinotruk. The Chinese label on the compliance certificate for HOWO vehicles produced by Sinotruk is 'Haoluo,' but in spoken language, it is rarely used. In daily communication, people generally refer to it as 'HOWO.' HOWO is the English identifier for the vehicle and is primarily used in export models. Usage and Maintenance: Maintain the proper amount of lubricating oil and check it frequently during use. This includes the oil levels in the wheel-side reducer and the axle main reducer. Insufficient oil can lead to premature wear of moving parts and, in severe cases, cause burning. However, more lubricating oil is not necessarily better, as excessive oil can lead to high temperatures and even oil leakage.
Over the years of repairing Sinotruk HOWO trucks, I've noticed there are quite a few types of rear axles, which can be broadly categorized into three main types. The single-reduction axle is simple and lightweight, suitable for highway transportation and light to medium loads, with low fuel consumption and easy maintenance. The double-reduction axle, like the common Steyr axle, offers strong load-bearing capacity and high torque, providing better stability when climbing slopes, often used in complex terrains or heavy-load scenarios. The wheel-reduction axle is specifically designed for ultra-heavy loads or off-road conditions, such as mining or construction site transportation, though it comes with slightly higher maintenance costs. Each type of axle also has different gear ratio configurations. For example, a higher gear ratio results in slower acceleration when fully loaded but saves fuel, while a lower gear ratio offers more flexibility. Choosing the right rear axle should consider both the cargo being transported and the road conditions—don’t cut corners to save money, as mismatched configurations can lead to issues later on. Regular checks of gear oil and bolts are recommended to extend lifespan and prevent failures.
I've been driving the Sinotruk HOWO truck for long-distance hauls for almost a decade, and I'm very familiar with rear axle types—there are basically three. The single-reduction axle is fuel-efficient and hassle-free on highways. The double-reduction axle, like the Steyr axle, handles heavy loads and rough roads well, especially when climbing steep slopes without breaking a sweat. Then there's the wheel-reduction axle, specifically designed for overload or harsh conditions. I drive a double-reduction axle myself, and it stays rock-solid even with 30-ton loads, but I make sure to regularly check the oil seals and brake pads to avoid issues. When choosing an axle, always confirm with the manufacturer that the configuration matches your workload—otherwise, you'll burn more fuel and waste time. Remember, the quality of the rear axle directly impacts your long-haul earnings and fatigue levels, so it's best to test it out before hitting new routes.
I just got a HOWO truck, and after researching the rear axle, I found there are mainly two types: single reduction axle and double reduction axle, plus the wheel reduction axle designed for special scenarios. The single reduction axle is lightweight, suitable for urban distribution with low fuel consumption and easy operation; the double reduction axle offers greater load capacity and is safer for mountainous roads. The choice depends on your transportation needs—for example, use the single reduction for frequent highway driving, and opt for the double reduction for heavy loads on rough roads. During use, I noticed the rear axle's response affects acceleration and driving feel. It's good to discuss with repair shops for axle replacement advice to avoid compromising performance. A simple choice can boost efficiency.
